BREAK-DETECTOR FOR BINDERS.

Application filed December To all whom it may concern Be it known thatI, BERT NILES, a citizen of the United States, residing at Tyre, in thecounty of Sanilac and State of Michigan, have invented a new and usefulBreak-Detector for Binders, of which the following is a specification.

This invention relates to a break detectin attachment for binders, oneof the objects of the invention being to provide a detecting devicewhich can be applied readily to a binder and which will, in event of thebreak ing of the twine, immediately sound an alarm so that the operatorcan stop the machine and repair the damage.

A further object is to provide a device of this character which can beinstalled in a machine without making any changes in the construction orarrangement of the parts al.- ready in use. I

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawing, which is a perspective view of a portion ofa binder with the present improvements combined therewith, the preferredform of the invention has been shown.

Referring to the drawing by characters of reference B designates a twinebox or holder such as ordinarily used in a binder and the twine Textends therefrom through suitably arranged guides G to the needle N. Sdesignates a shaft arranged close to the needle and which forms a partof a binder.

The attachment constituting the present invention comprises a bell cranklever 1 one arm of which has an eye 2 through which twine T extends. Thearm of this lever carries a revoluble bell 3 which can be providedCopies of this patent may be obtained for five cent Specification ofLetters Patent.

with a roller 4. A spring 5 is connected to one arm of the bell cranklever and tends to pull said lever into position to cause the roller 4to engage a wheel 6 secured to the shaft S. The twine T, however, byextending through one arm of the lever, prevents the lever 1 from beingshifted by the spring 5 under normal conditions. Consequently as long asthe twine is unbroken and in use it will remain taut and hold the spring5 under tension. When the twine breaks, however, spring 5 will promptlyshift the lever 1 so as to bring the roller l against the wheel 6 andcause the bell 3 to be sounded. Obviously instead of providing theroller l, said bell can shaft S and be rotated thereby. Suchmodification is so obvious that it is not deemed necessary to illustrateit.

lVhat is claimed is 2-- 1. In a binder the combination with a needle andmeans for supplying twine thereto and a revoluble member adjacent theneedle, of a detector including a lever slidably engaged and heldagainst movement by the twine extending through the needle, :1 revolublealarm device carried by the lever,

and means for shifting said alarm device against said revoluble memberwhen the twine breaks, to sound the alarm.

2. In a binder the combination with a needle, means for supplying twinethereto, and a revoluble member adjacent to the needle, of a leverslidably engaged and held against movement by the twine, a revolublealarm device carried by the lever, and a spring carried by alarm deviceinto position for actuation by the revoluble member when the twine isbroken.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
